Your Locks. Made Smart. No Rip-and-Replace.
The GRIT Latch controls any powered-to-lock or powered-to-unlock mechanism already on your doors. Per-user permissions, scheduled access, emergency lockdown, and a complete audit trail — without replacing a single lock.
Physical Keys and Manual Access Are Holding You Back
Facilities with multiple doors, shifting personnel, and compliance requirements face the same problems every day.
Who has keys? Which doors do they open? Keys get copied, lost, and passed around. When someone leaves, you re-key everything — or hope for the best.
Who entered the building at 2 AM? Did the contractor leave after the job? Without badge-level tracking, you're guessing from a parking lot head count.
Fire alarm sounds. Who's actually in the building right now? Paper sign-in sheets are never current. Generating an accurate head count during an emergency takes too long.
Temporary workers need access for a day, a week, or a project. Issuing and collecting physical keys for short-term personnel is a logistical nightmare.
Every employee departure means rekeying doors or accepting the risk. At scale, locksmith visits and new key distribution become a recurring budget line.
Which door did they use? When did they enter? How long were they inside? Without electronic logging, incident investigation is guesswork and liability is exposure.
Your Locks. Our Brain. Complete Control.
The GRIT Latch is a BYOL (Bring Your Own Latch) controller that works with any powered lock mechanism already on your doors. Electric strikes, maglocks, motorized locks — if it takes a signal to open, the GRIT Latch controls it.
No Permission. No Entry.
Every door is gated by an RFID reader and the GRIT Latch. Badge tap triggers an instant permission check — if the user is authorized, the latch releases. If not, the door stays locked.
- ✓ Per-door, per-user permission control
- ✓ Works with existing RFID badges and IDs
- ✓ Scheduled access windows by time and group
- ✓ Remote unlock from any device
- ✓ Emergency lockdown with one click
- ✓ Temporary access for contractors and visitors
Every Door. Every Entry. Logged.
Every badge tap — authorized and denied — is recorded with timestamp, user, and door location. Live occupancy shows who's inside right now, critical for emergency muster.
- ✓ Complete entry/exit audit trail
- ✓ Real-time occupancy dashboard
- ✓ Instant emergency muster reports
- ✓ Exportable logs for compliance
- ✓ Denied attempt alerts
- ✓ Incident investigation support
The same badge that opens the door can start the clock. When door access and time tracking share a badge, walking through the entrance logs a shift start automatically. One tap, two systems handled.
How It Works
Wire the GRIT Latch into your existing powered lock mechanism — electric strike, maglock, or motorized lock. Mount a Track Reader at the door. No lock replacement needed.
Set per-door, per-user access rights from the Hub dashboard. Define access windows by time of day, day of week, and user group. Bulk import users via CSV.
User taps their RFID badge — employee ID, HID card, student ID, or NFC phone — to the Track Reader mounted at the entry point.
The Hub checks permissions in under a second. Authorized? The Latch releases. Unauthorized? The door stays locked. Either way, the attempt is logged.
Every entry, every exit, every denied attempt — timestamped with user identity and door location. Exportable for compliance, investigation, or muster reports.
Unlock a door for a visitor from your phone. Revoke access instantly. Trigger emergency lockdown across all doors with one click — from anywhere.
Built for Facilities. Built to Retrofit.
Works with any powered-to-lock or powered-to-unlock mechanism on your doors. Electric strikes, maglocks, motorized locks — keep what you have.
Grant access to specific doors for specific people. Maintenance enters the mechanical room. Managers enter the server closet. Everyone else sees a locked door.
Daytime for staff, evenings for the cleaning crew, weekends for authorized personnel only. Time-based rules per user group, enforced automatically.
Let in a visitor from your phone. Grant temporary access from your desk. No need to walk to the door — unlock remotely from any device on your network.
One click locks every door in the facility. Instantly. From the dashboard, from your phone, from anywhere. When seconds matter, you don't fumble with keys.
Live dashboard shows who's inside the building right now, which door they entered, and when. Critical for emergency muster and shift handoffs.
Every badge tap — authorized and denied — is recorded with timestamp, user, and door. Export logs for compliance, incidents, or insurance documentation.
HID proximity cards, employee IDs, student IDs, NFC-enabled phones. GRIT reads what your people already carry — no new badge system to deploy.
